"Subject's anatomy suggests a highly developed species of analogous physical durability to mankind. Physical structure, general organic processes and reproductive anatomy all show remarkable similarities. Is this racial parallelism purely coincidental?"There are Human Aliens which are indistinguishable from humans (at least on the outside appearance). Then there are Rubber-Forehead Aliens, which look like humans but with some minor differences. Then there are Humanoid Aliens that have the general shape of a human, but definitely look nothing like us. Be it a different number of fingers, different skin, feathers, whatever. Only similarity they need is one head, two arms, two legs, and a generally upright stance, tail and/or wings optional. Any further deviation from the humanoid form is likely to result in Starfish Aliens. Like Human Aliens and Rubber-Forehead Aliens, the prevalence of this trope — in live-action TV in particular, though also in movies and comics and other primarily visual media — tends to have a lot to do with the need to create something that human actors can comfortably portray, that human artists can conveniently and quickly draw, and that human viewers/readers can intuitively empathize with (and they tend to stay farther away from the Uncanny Valley than more human-looking aliens, and are thus less frightening). Anyone defending the trope as not entirely unrealistic could appeal to convergent evolution — the idea that similar environments facilitate similar patterns of isomorphic development in different species — though it might be a bit of a stretch to expect humanoids even so. Of course, we don't know any actual aliens that we could use as a basis for comparison for what's realistic. May overlap with Petting Zoo People or Intelligent Gerbils. Ursine Aliens often fall under this, since bears can appear very humanoid by themselves.

Anime And Manga
- Dragon Ball Z - The Saiyans could fall into either this or Human Aliens. Aside from them, the vast majority of aliens are in this category. Though most are possessed of unusual height, horns, elongated heads, a tail, etc., a handful are simply human forms with the only deviation being unnaturally-colored skin - Jeice and Sauzaa come to mind.
- It's been revealed that Jeice and Salza were actually both members of the same species. Like humans they come in multiple skin colors; unlike humans those colors are red and blue.
- In Captain Earth, what we mostly see of the Kiltgangs when not in their human avatar bodies, is their true forms as Humongous Mechas. However, they simultaneously also have a second form, a sort of piloting form that is officially called "Gig Mode", in which they all look vaguely like their avatar bodies, only incorporating their character colors more and adding some details that reflect their outer mecha bodies and abilities, like armour plates, hats (or some other forms of head additions) and the like. The anime underlines this otherness of their forms by using colored outlines for them. However, it is unknown wether these forms could or do exist outside of their mecha bodies as well.
- In Naruto, Kaguya, the mother of the Sage of Six Paths and his twin brother, came from another world. She looked human enough (possibly enough to qualify as an example of Human Aliens), barring the horns and third eye. The sons she sired with a presumably human father had smaller horns and lacked her third eye. Most of her alien features faded with each generation, to the point that most of her descendants in the present day are indistinguishable from humans.
- Most aliens in Buck Godot: Zap Gun for Hire fit this trope, although quite many are Starfish Aliens or animal-like (Rubber-Forehead Aliens have appeared a few times, but not very often). Some aliens don't quite fit this trope, like the Prime Movers who look like Rubber-Forehead Aliens from the waist up, but have several short stubby legs, or the Klegdixal, who have a humanoid body shape but seem to lack legs (or any facial features except eyes, for that matter).
- Warlord of Mars has the Green Martians, who are exceptionally tall, have six-limbs and tusked mouths. They are easily the most inhuman of all other sentient people in Barsoom, who look just like humans with exotic skin colors. Justified by the fact that the Green People were the end result of crossbreeding between white apes, apts and Red Martians.
- Warriors of Mars has the Thithers, who are even more monstrous than the Green Martians, except they are red-skinned and vaguely crustacean. The one thing keeping them from the next level is that they are bipeds who walk on their legs and have a head and body like humans.
- The Kahori in the comic relaunch are scaled, grey-skinned humanoids who walk on hind legs.
- In Superman/Supergirl story War World two different alien races show up: the Largas and the Warzoon. The former are tall, human-like aliens with white-silvery skin, long fingers and faceless heads. The latter are red-skinned, fanged humanoid aliens with ape-like flat faces, huge, bulging, blank yellow eyes and four-fingered hands.
- Bad Planet features aliens of many shapes and sizes and the closest ones to this trope are the Phaedons, an nearly extinct race of large, grey humanoids with extra eyes.
- Tyrant Kings has the Terran Systems Alliance note how nearly every Citadel race is extremely humanoid with relatively minor differences. Given that the sentient races of the TSA includes not only humans but also tyrannosaurs, ceratopsians, raptors, pterodactyls, dilophosaurs, and Protheans (called Martians), they're generally creeped out by the similarities.
- Alien's Xenomorphs.
- The Xenomorphs are excused, since they take on the traits of their hosts. In Alien 3 we see one that was a quadruped because it burst from a dog, AVP 2 has one that look like a Predator, including the "dreadlocks" and mandiblades (fits into the trope, but solely because the Yautja host does.) Other examples are fully straight.
- Even more so, the Predators (Yautja).
- In Prometheus the proto-Xenomorph "Deacon". Its former host, the Engineer, straddles the line between this and Human Aliens.
- The Na'vi from Avatar are ten-foot-tall, blue-skinned, yellow-eyed, cat-nosed, four-fingered and four-toed (note, however, the titular Half-Human Hybrid Avatars have five), with what is essentially an organic network cable that looks like a braided ponytail.
- Animals on Pandora are in two main types; four-limbed and six-limbed. Some people claim that there are no other four-limbed animals, but have not checked their facts.
- Seeing as how the life on Pandora is connected by a 'brain-like' biological network, it's possible that the evolution of life on the planet was guided by this mind. This would also explain why the Na'vi are capable of linking their minds with every other animal, which would require an improbable amount of co-evolution from a Darwinian standpoint. Pandora's biology is not necessarily Earth's biology.
- They were evolved from the same ancestor as the ape-like Prolemuri which have four partially fused arms with two fingers on each. The Na'vi just had those arms fuse together all the way.
- Animals on Pandora are in two main types; four-limbed and six-limbed. Some people claim that there are no other four-limbed animals, but have not checked their facts.
- The aliens in District 9 have two legs, one head and two eyes, but that's as much as they have in common with humans. They have four arms including the smaller, almost vestigial arms house in their torso. They largely resemble seven-foot tall humanoid cockroaches, and even their vocal chords are too alien to try to mimic human speech.
- The title character in Paul.
- The aliens in Wham Bam Thank You Spaceman
- Many aliens in Star Wars (jointly described as humanoids, in fact). Famous examples include the Wookiees (hulking simian/ursine aliens that look like Bigfoot); Ewoks (ursine aliens that resemble three- or four-foot teddy bears); Gungans (amphibian/fish people that include Jar Jar Binks); Aqualish (walrus-like humanoids, pictured above); Trandoshans (lizard-like humanoids); and Gamorreans (pig-like humanoids). The other common kind is the rubber foreheaded near-humans, who share an ancestry with baseline humans, though there are some genuine examples of Starfish Aliens (including, famously, the Hutts). There are also cyborgs (some human and some not) and crossbreeds of similar (usually hominid or vaguely hominid) species.
- Pretty much every alien in the Ratchet & Clank film is this.
- Most of the aliens in Lilo & Stitch are some form of this. Three of them are even able to pass for human with a Paper-Thin Disguise, and it's just unrealistic enough to be funny.
- This trope plays out in the Alterien series by Adam R. Brown.
- He's an exceptionally tall man with many of the same features as Alteriens in their true form. However, he has rounded ears and polydactyly on both his hands and feet. He has five fingers and a thumb on each hand and six toes on each foot. Apart from that, he looks very similar to humans.
- The Alteriens in their true form are like this with their pointed ears, somewhat larger than normal heads and eyes for their respective builds and lack of eyebrows. Additionally, the only hair on their entire bodies is from their heads. They were modeled after the Sisters of Orion and other similar Shanda'ryn hybrids.
- Larry Niven averted this for the most part in his Known Space universe, but used the Kzinti, who are cat people.
- The striivic-na in the Warchild Series have the general shape of humans, plus/minus a few details...
- In Childhood's End, the Overlords superficially look somewhat human, but on closer examination are far more alien.
- Most of the alien races in Revelation Space Series are Starfish Aliens, but the Amarantin were humanoid birds.
- The Ra'zac of the Inheritance Cycle.
- Molt Brother
- Robert Westall's Urn Burial's Fefethil and Wawaka cat people and dog people, respectively. Starfish Aliens do get a mention, but none appear as characters.
- The Destroyermen series takes place on an alternate Earth where the Cretaceous extinction apparently never happened. The two dominant species are the Mi-Anaaka (called Lemurians by the titular destroyermen), a humanoid species descended from Madagascar's lemurs, and the Grik, a species of predatory dinosaur descendants that look pretty much like their ancestors.
- Both played straight and also frequently averted by E.E. "Doc" Smith.
- The inhabitants of the Skylark universe's Green system and even the monstrous Fenachrone fit into the same general framework of 'upright biped' as do humans and the Jelmi are indistinguishable from humanity, but the Chlorans are utterly alien.
- Frequently averted in the Lensman universe, however. True, there are a lot of non-Earth-origin species which fit this trope, but the degree to which utterly alien species are to be found on both sides of the conflict (and especially among the "good guys") stands out even today. Barring his wife Clarissa, eventually, not one of Kim Kinnison's fellow Second-Stage Lensmen is even remotely human in appearance. One of them (Nadreck) can't even coexist in the same room without special equipment, and even with it he can't stay very long.
- In Wen Spencer's Ukiah Oregon series, Hex and Prime, the only survivors of the initial Ontongard invasion horse, had bodies that looked largely human, but with all black eyes, strangely textured hair, and slightly odd proportions.
- The Parshendi of The Stormlight Archive are of generally humanoid shape, but have marbled black and red skin and are limited shapeshifters, able to assume a number of different forms as needed (including warform, which causes them to grow armor plate; workform, which is strong but nonviolent; and mateform, which is capable of reproduction).
- Many of the species in the My Teacher Is an Alien series, although there are quite a few examples of Starfish Aliens as well. The ones closest to human in shape, Broxholm, Kreeblim, and Hoo-Lan, can pass for human if they wear Latex Perfection disguises, though only Hoo-Lan is close enough to be a borderline Human Alien (though child sized and blue).
- The Vegans in This Immortal. They are rpughly human-shaped but are blue-skinned, amber-eyed (or at least Cort Myshtigo is) and the vents for their lungs can be found of their torso. Additionally, their bodies are covered in patterns invisible to humans, enabling Vegans to identified each other's clan by pattern.
- Discussed in Jon Stewart's Earth (The Book), who explains that humanity's ideas on what aliens might look like most frequently ended up being variations on themselves with "a piece of metal shit on their face to make them look spacey". Interestingly, the book itself seems to avert this, as several parts appear to acknowledge the fact that the aliens who will read this book might be completely different from us (maybe even Energy Beings).
- There is a variety of races in Mikhail Akhmanov's Arrivals from the Dark books. The races that fit this trope include the Bino Faata (most book protagonists are descended from a human-Faata hybrid), the Kni'lina (vegetarians with no facial hair), the Haptors (big Proud Warrior Race Guys with horn-like bumps on their heads), the Teruxi (a race of extremely-attractive humanoids with a Free-Love Future mentality), the Nil'hazi (an aggressive female-dominated race), and dozens of primitive humanoid races introduced in the Trevelian's Mission spin-off series. The near-humanoid races include the Lo'ona Aeo (Space Elves with four sexes and four fingers on each hand, who reproduce like the asari), the Paraprims (hairy primate-like Telepathic Spacemen), and the Llyano (primitive tribal arboreals). The races that completely avert this are the insectoid Arkhs, the shapeshifting Proteids, and the worm-like Silmarri.
- The History of the Galaxy doesn't really have that many alien races, but, of the ones that are present (and described), only three fit this trope: the blue-skinned Harammins, the Heavy Worlder Norls, and the more human-like Emulotti. The races averting the trope include the Insects, the two-headed Logrians, and the Evolgs.
- The Drake Maijstral series by Walter Jon Williams has the Khosali, who long ago conquered Earth, and who therefore would probably prefer to consider us "Khosalioid Aliens". They are taller, on average, than humans, and covered with fur, and they have pointy faces, and some of their joints work slightly differently from ours. But overall, we were lucky that they were so much like us, as it made fitting into their culture, after we were conquered, that much easier.
- The four oxygen breathing species in the Chanur Novels are Humanoid Aliens (with the three methane breathing species being Starfish Aliens):
- The hani are standard Cat Folk.
- The mahendo'sat are covered in short, curly fur and have blunt, non-retractable claws.
- The kif have long snouts which come equipped with two sets of jaws rather than one.
- The stcho are skinny, hairless and have large, pale eyes.
Live Action TV
- Farscape species with repeat appearances:
- Hynerians - 2-3 foot tall stumpy limbed frogs with really big eyebrows.
- Scarrans - Giant lizard men. Range from human but scaly to spaaaaaace tyrannosauruses.
- The Ancients - Insectoid, but generally look human via Voluntary Shapeshifting. And that's just the ones that have been altered to survive in our dimension; we don't even glimpse what the True Ancients really look like.
- Diagnosans - Skeleton thin, two slits instead of a nose, and a bulbous head.
- Some aliens in Star Trek, such as the Breen and the Gorn. Most tend to be of the rubber forehead and human variety though.
- Babylon 5 had several, like the Narn and the Pak'Mara.
- In Andromeda, the Than-Thre-Kull and the Magog.
- The various Stargate franchises have mostly Human Aliens, but several species are different:
- The Asgard are The Greys, although, in distant past, they used to look more human.
- The Unas are tribal Lizard Folk.
- The Ohne are advanced Fish People, as are the catfish-like aliens of Stargate Universe.
- Jup and Tenat of the Lucian Alliance were the only shown members of an unspecified race who are clearly Rubber-Forehead Aliens.
- The Reol are a race of beige-skinned humanoids with dreads and wrinkly skin who can make you think they're your best friend.
- The Gadmeer are only shown in an image but appear to be bipeds of either reptilian or insectoid type.
- The Ursini in Stargate Universe. Despite the name, they don't look at all bear-like.
- Doctor Who
- Ice Warriors
- Clomians (AKA Abzorbaloffs), from their twin planet
- Cheetah People
- Butterfly People
- The Moxx of Balhoon
- The Graske, from the 2005 interactive game Attack of the Graske
- The Sarah Jane Adventures
- Raxacoricofallapatorians, Sontarans and Graske, like its parent show Doctor Who
- The Shansheeth
- On Alf, the aliens from Melmac look like a cross between dogs and aardvarks, and they also have a bit of Bizarre Alien Biology. But they still had a mostly human culture. And they could build spaceships, which could take them all the way to Earth. Strangely, their planet also had cats.
- In Starfire, the various alien species humanity goes to war with include Cat People (the Khanate of Orion), Bird People (the Ophiuchi), Bear People (the Rigellians), and 4-Armed People (the Gorm).
- The majority of Warhammer 40,000's races are Humanoid Aliens. For example, the Tau are short humanoids with grey-blue skin and hooves, the Orks are large humanoids with green skin and a fungi-based biology and the Kroot are gangly yet disproportionately strong humanoids with avian features and the ability to direct their own evolution. The Eldar, are the most similar looking as their features closely resemble human ones when armoured, but their bodies are almost impossibly thin outside of it. Necrons are formerly biological beings now contained in living metal with a form resembling a skeleton, while some of the more mutated followers of chaos could be considered more humanoid than human.
- In Xenology, a background book, the dissecting bio-technician notes the remarkable similarity between the major races of the setting, and how several of them seem to have been artificially constructed. Humanity may or may not have been made by the same beings that made the Eldar and the Orks among others, which would explain their gross similarity.
- The Hrud straddle the line between this and Starfish Aliens. While early editions of the game had Hrud as spacefaring Rat Men, the design has since been changed to ghastly barely-humanoid shambling things with multi-segmented ribbons for limbs and truely Bizarre Alien Biology. The abovementioned Xenology mentions that Hrud carcasses decompose so quickly it's difficult to find one worth dissecting.
- In some editions it's explained that most of them have a common origin, although how canon this is in the current fluff is up in the air. One story goes that the Necrons were the first humanoids, the Old Ones created the Eldar, Orks and the seldom-seen apelike Jokaeros to fight them, then the Necrons manipulated the evolution of Earth's mammals to create a new Super Soldier race to counter the Old Ones' creations, which eventually became the humans (the experiment was largely considered a failure because the Anti-Magic Pariah Gene they were trying to cultivate turned out to be vanishingly rare). Later on some Eldar scientists (believed to be working for Magnificent Bastard par excellence Eldrad Ulthran) genetically engineered the Tau from a sheeplike animal for as-yet unrevealed reasons, while the Tau's favorite client race, the Kroot were originally birdlike but absorbed some Ork DNA due to their peculiar digestive processes.
- A borderline example is the Kaorti of Dungeons & Dragons. Debuting in the third edition Fiend Folio, these Gigeresque humanoids are the result of either humans or elves (depending on the version of the backstory) experimenting with the Far Realm. The "borderline" descriptor is for two reasons: Firstly, the Far Realm is not the same thing as outer spaaaaaace but is rather an incomprehensible plane of existence inspired by Lovecraftian horror. Secondly, while they do appear superficially anthropomorphic, they otherwise resemble the aforementioned xenomorphs and are composed of a strange, toxic resin instead of bone and flesh.
- In Traveller the Aslan and Vargr are four limbed with two limbs for walking and two for grasping. However their appearance also resembles some Terran animals(lions and wolves respectively). In behavior they are roughly comparable to humans-at least enough for them to vaguely comprehend one another.
- Every playable alien species in the Rocket Age solar system bar the Metisians is a humanoid alien; from the apelike Venusians, the various castes of Mars and the plant-based Ganymedians
- Achron has the Vecgir, which are roughly a meter taller than the average human and have an extra set of arms and a sort of reptilian appearance. Compared to the other alien race in the game, the Grekim, the Vecgir are downright charming.
- The Iskai from Albion are tall, fast-moving and nimble but frail mammalian humanoids with faces that resemble those of great cats, mostly short hair all over their bodies, tails that can be used to manipulate objects and use weapons, four nipples, a somewhat telepathic forehead organ called a Trii, cat-like feet and on them claws that unlike Earth vertebrate claws are bony and presumably part of their skeletons. They're basically as different as humanoids could be from humans while still unintentionally appearing to be related to them, although those claws would be a little puzzling if they really were.
- Tran, Beatmania IIDX's Series Mascot, has white hair, has simpler details than other human characters, sports two light blue pupil-less eyes, and has no other facial features.
- The majority of the Covenant species, with the exception of the Hunters, the Engineers, and the Drones.
- While The Flood infect plenty of humanoid species, their "purer" forms are an aversion.
- The Forerunner Saga and Halo 4 reveal that the Forerunners also fit this trope; it's implied that Forerunners and humans have a common ancestor. Completely averted with the Timeless One, though, which resembles some kind of enormous crab and is a Precursor which also happens to be a Flood Gravemind.
- Mass Effect.
- The vast majority of the alien species fall into this trope, with the asari and the quarians being Rubber-Forehead Aliens. The elcor may not seem humanoid at first, but that is because they walk on all fours, use their powerful forearms and fists to support themselves, much like gorillas. This is due to having evolved on a high gravity world, where falling over often means not getting up again.
- The few known exceptions are the hanar, the Reapers ( and their creators, the Leviathans), the rachni, and the keepers.
- The novel Mass Effect: Revelation briefly mentions that there's quite a few Epileptic Trees among humans as to why, exactly, the humanoid body structure is so common. Then-Lieutenant David Anderson subscribes to the simplest theory: that there's just some as-yet-undiscovered evolutionary advantage to it. Out of universe, of course, it's a time and budget thing coupled with the way Unreal Engine 3's character animations are implemented: each new creature type requires a different skeleton to be programmed (hence why the less-humanoid species are rarely shown moving around).
- Plus, on the playable side of characters, they all need to be able to use the same weapons and (mostly in the first game) armor.
- Meteos has a number of these, differentiated by different skin colors or head shapes. An example would be the Geolitians, the starting race who are light blue in skin color and have antennae/horns on the sides of their heads that curve upwards.
- Giegue of the MOTHER series was this in combination with The Greys before he went off the deep end.
- Both the Space Pirates and the Chozo from Metroid. The Space Pirates are obviously non-human, but have advanced technology and some kind of language. The
extinctChozo, being also Sufficiently Advanced Aliens, had even more advanced technology (such as Samus' power suit), and some kind of language that despite their technological prowess is mostly found written in stone ruins. Appearance-wise, they resemble an anthropomorphic cross between a manta ray and a parrot on two legs. The Pirates, on the other hand, appear either reptilian or lobster-like, depending on which specific game they're in. The KI Hunter Pirates slip into Big Creepy-Crawlies or Star Fish Aliens though.
- Some Pokémon.
- Star Control has the Arilou Lalee'lay and the Shofixti (upright-walking marsupials). A few others are added in the third game.
- It's implied that the Arilou may have tinkered with human genetics at some point in our past, which could explain the resemblance.
- The Protoss in Starcraft definitely qualify. They've got the "human" number of heads, arms, legs, and eyes, but they also have digitigrade legs, nerve cords coming out the backs of their heads, and skin (scales?) in a wide variety of cool colors. Also, they have No Mouth, because they're, apparently,photosynthetic .
- World of Warcraft's draenei, which are something of an expy of the Protoss, are somewhat more human-looking: They look like blue, catfish-whiskered classic demons.
- Many races throughout the Warcraft series are technically humanoid aliens. Orcs are originally from Draenor, not Azeroth (so technically the other races are all orcoid aliens in the parts of the games that take place on the former). Much of the burning legion is made up of aliens, most prominently the Man'ari eredar and the Dreadlords.
- The Pikmin themselves have an unknown degree of intelligence, but whatever Olimar himself is is pretty weird too. He's basically humanoid but under an inch tall. Oxygen is toxic to him. He has few hairs, and when they fall out thanks to stress they make a "hissing sound". He's got weird talents with whistling. He says the following in one of his voyage logs, contrasting it to how Pikmin come from and return to the soil.
"My people were borne out of the sea of stars to come down to Hocotate, and when we complete out lives, we return to the great ocean of stars."
- The Vasudans in FreeSpace are humanoid, albeit with apparently mechanical additions. Averted with the Shivans.
- Ratchet and Clank with protagonist Ratchet for example.
- Cryto from Destroy All Humans! is a good example.
- In X Rebirth, the Teladi Lizard Folk share many features with humans and have roughly similar facial features. However, the teladi have an odd forward-leaning posture due to their large tail and alligator-like limb structure. In the previous games the video communication busts indicated a much more human posture and traits such as an affinity for clothing and in the case of teladi Space Pirates, nice hats.
- Plenty of alien races in FTL: Faster Than Light are humanoid in shape. The Engi look like minimalistic humanoids despite being able to take many forms, the Zoltan are Energy Beings who take a humanoid shape, Rockmen look like golems and Lanius are humanoids who can meld with metals. The Mantis and Slugs are exceptions though, looking like scaled-up versions of their namesake species.
- The Engi are a justified example in that the ones you can recruit choose to be that shape for convenience, and it's strongly implied that Engi spacecraft are technically the same species as their crew, or at least closely related.
- The aliens in Allen The Alien look like humans with antennae.
- The Mentakans in Cwynhild's Loom, as seen in a flashback, are large, purplish humanoids.
- El Goonish Shive
- Uryuoms are humanoid shape shifters who in appearance are a mix of Little Green Men and The Greys but as shapeshifters can appear completely human if they have a human form among their personal cache of possible forms.
- The lespuko being a genetic relative of the uryuom are also humanoid in build but more animalistic than them.
- Enemy Quest: Most of the alien Visitors share a basic humanoid shape with some differences. The Skut don't count because they look like short dog/rodent/lizard hybrid creatures with six eyes.
- Most of the alien species seen so far in the webcomic Inhuman are humanoid - it has been mistaken for a Furry comic, to the artist's great annoyance.
- Homestuck has the Cherubs; green skeleton-like things. Trolls -grey, vaguely insect humanoids with grey skin, horns, and fangs- could fit either here or as Rubber-Forehead Aliens.
- Most aliens in Luminary Children look a lot like humans.
- The Pracs in Xenospora are basically humans with animal ears.
- Most aliens in Zukahnaut fit this trope.
- Most denizens of the Runners 'verse, including Cember's species which has vestigial radial symmetry (indicating it has evolved from something more starfish than human-ish).
- Almost all species met in Captain Ufo so far are like this. The remaining ones are Starfish Aliens.
- The Mercury Men, also called "the first men" in the titular series, are humanoid in appearance, but are taller, thinner and stoop (supposedly because of Earth's greater gravity). They are also composed of Hard Light and apparently have a Third Eye.
- This article from Cracked suggests that if aliens exist, they are likely Humanoid Aliens, Human Aliens, or Rubber-Forehead Aliens.
- Nearly every alien on Ben 10 that Ben can transform into, with the only exceptions being Xlr 8, Ripjaws, Wildmutt, Ghostfreak, and technically Four Arms.
- Quite a few in Futurama. The Decapodians, who are humanoid crustaceans. Kiff's species, Nibblonians, and many other species that were never named.
- The Traags/Draags of Fantastic Planet. Aside from their size, they're essentially hairless, blue-skinned, red-eyed humans.
- The unnamed alien tribe from Skywhales.
- The Titans and Nebulans in the Transformers Generation 1 cartoon - both have pointy ears and either blue or green skin. In the comic, however, the Nebulans were indistinguishable from humans.
- These are more Rubber-Forehead Aliens, really. The Transformers themselves, on the other hand, definitely qualify. They're Mechanical Lifeforms, but most have one mode with a humanoid body plan... And some even have more than one, for one reason or another, while others have one and are part of another.
- Heck, there's even a small handful of Transformers that don't have humanoid robot modes individually, but are still part of a humanoid Combining Mecha.
- Pretty much everyone in Team Galaxy.
- Starfire and her species for example in Teen Titans.
- A ton of aliens including Mira in Buzz Lightyear of Star Command.
- The cast of Lloyd in Space.
- Pretty much everyone Betty fights in Atomic Betty.
- Zim's species in Invader Zim.
- Countless characters in Star Wars: The Clone Wars.
- The criminals in Men In Black The Series.
- Defenders of the Earth has the following examples:
- The Krel from "The Creation of Monitor"
- Shogoth from "A Demon in His Pocket"
- Krone and Axrel from "The Sleeper Awakes"
- Beastmaster from "Diamonds are a Ming's Best Friend"
- The Night Giants from "Doorways Into Darkness"
- Roarke and his crew from "The Starboy"
- Brutan from "The Time-freezer"
- Graviton from the "Necklace of Oros" arc
- The Gorlocks for example from The Adventures of Jimmy Neutron: Boy Genius in the episode "Win,Lose and Kaboom".
- Some of the aliens such as Billy that work at the center from Martin Mystery
- Rick and Morty includes many humanoid alien species, including the Gazorpians and the species assimilated by Unity.
- The popular image of The Greys presents them as Little Green Men... only greyer.
- The Reptilians tend to fluctuate between this, Rubber-Forehead Aliens, and even less human-like Lizard Folk.
- Ulti's Bar & Grill has the worlds of the Dark Legion, which have a variety of aliens among them. Many of these said aliens are humanoid in appearance, if not really anywhere near a human in ability or specifics.
